can you try changing that last line to:

base = zephyr

And then try to delete your current build configuration, restart VS Code and try to generate the build configuration again?

Best regards,

So basically my workflow will be like this, openning an existing application or creating one, when it is created i will go for the build configuration, so in the build configuration menu everything is fine and normal, i can see the tool chain i can see the sdk version and everything, so after that i can do the generate and build too, it will build when i am in that menu, after that when i go to the actions menu for the flash option it wont be there, it asks me to build again over there showing that two icons pristine build and output channel, so when i click the pristine build it shows that error " Unable to build: SDK not found. Ensure that a valid SDK is used for the build configuration."

i also tried with a different version of sdk the issue presists the same,

okay my contents in the config file is as below

[manifest]
path = nrf
file = west.yml

[zephyr]
base = C:\ncs\v3.1.1\zephyr

RE: Help needed with Pristine build in vs code

Edvin — Tue, 20 Jan 2026 13:55:31 GMT

Also, can you please share the content of your: v3.1.1\.west\config file?

BR,

Edvin

RE: Help needed with Pristine build in vs code

Edvin — Tue, 20 Jan 2026 09:42:03 GMT

When you create your build configuration, does v3.1.1 show up as an option? And how about the toolchain? Does it appear there?

Does it build the first time after you click "generate and build" in the "Add Build Configuration" tab, but then later doesn't find the SDK version? Or does it not build at all the first time around either?

Is this only an issue for v3.1.1? Or is it an issue for older NCS versions as well? Can you try with e.g. v3.0.1 and see if the issue is the same?

Best regards,

Edvin

Vishveshwaran — Tue, 20 Jan 2026 03:31:37 GMT

so basically i tried what you were saying,

and even added the build configuration and it still looks like this

it dint change anything here

Can you try: in VS Code, press file -> open folder, and open the root folder of your SDK (the one named v3.1.1). Then press the "+" sign ("open an existing application"), navigate to your application folder, and select "Open". This adds the application to the workspace, without removing the SDK from the workspace. Then you can generate a new build configuration:

And you should see the SDK version and toolchain version in the two upper options.

Edvin

Vishveshwaran — Mon, 19 Jan 2026 09:43:06 GMT

this is the ncs folder which i am having.

and my manage tool chain menu looks like the above, and moreover when i click the open sdk directory in the manage sdk menu it is opening the C:\ncs\v3.1.1 folder only, am i missing something, it is a nRf Connect SDK (NCS) right

RE: Help needed with Pristine build in vs code

Edvin — Mon, 19 Jan 2026 09:30:42 GMT

Still doesn't make complete sense to me.

Do you mean a normal NCS (nRF Connect SDK)? Or Zephyr only, without the nRF part of it?

What folders are present in the root folder of your SDK? Can you please send a screenshot?

Best regards,

Edvin

RE: Help needed with Pristine build in vs code

Vishveshwaran — Mon, 19 Jan 2026 03:35:45 GMT

NCS with zephyr only. i do have the sdk version with the zephyr.

RE: Help needed with Pristine build in vs code

Edvin — Thu, 15 Jan 2026 12:48:32 GMT

NCS without Zephyr? Or do you mean Zephyr without NCS?

RE: Help needed with Pristine build in vs code

Vishveshwaran — Thu, 15 Jan 2026 12:23:18 GMT

Yes that is what happened, the ncs folder got disconnected from the nrf extension alone, but still works with the workspace as i told the terminal based build is working. I am using an official release only of the NCS which do have the zephyr

RE: Help needed with Pristine build in vs code

Edvin — Thu, 15 Jan 2026 11:53:36 GMT

Ok, the nRF Connect for VS Code plugin will only work if you are using an NCS release, as far as I know. So unfortunately, if you are using standalone Zephyr, it will probably not work. The reason is that the plugin needs to know where NCS is located, to select the correct SDK to build with your application. If you can't point to the SDK, it doesn't know what to do.

It is possible to have the SDK isolated from the application folder, but it still needs to be an NCS release. You can also modify the source files in the SDK, such as merging particular pull requests and using the main branch instead of a stable release.

What are you trying to use? Zephyr (without NCS)?

Best regards,

Edvin

RE: Help needed with Pristine build in vs code

Vishveshwaran — Thu, 15 Jan 2026 08:57:12 GMT

As i was saying, im using nrf connect for vs code for the past 6 months i did all these before itself, my sdk wasn't found in the previous screen shot since i was using a dedicated project file which was isolated from the original sdk version thats why it couldn't find that, i do have the sdk and the build is still doable when i run the west build commands in the nrf terminal. But pristine build in the ui isn't working.

RE: Help needed with Pristine build in vs code

Edvin — Thu, 15 Jan 2026 08:53:30 GMT

... And? Did it work? Does it recognize the SDK version after this?

BR,
Edvin

RE: Help needed with Pristine build in vs code

Vishveshwaran — Wed, 14 Jan 2026 10:03:06 GMT

done

RE: Help needed with Pristine build in vs code

Edvin — Wed, 14 Jan 2026 09:47:33 GMT

Is it possible to choose v3.1.1 from the dropdown menu on top? The one named "SDK"?

If so, try that, and see if that solves it. If it is not an option, try installing that SDK via the VS Code extension:

Can you please show me a screenshot of the window where you generate your build configuration:

RE: Help needed with Pristine build in vs code

Edvin — Mon, 12 Jan 2026 13:46:06 GMT

Hello,

Can you please generate and upload the support information in nRF Connect for VS Code? It is generated by clicking this button:

Does that list v3.1.1 under "sdks", like this:

  "sdks": [
    {
      "version": "v3.2.1",
      "path": "c:\\ncs\\v3.2.1"
    },
    {
      "version": "v3.2.0",
      "path": "c:\\ncs\\v3.2.0"
    },
    {
      "version": "v3.1.1",
      "path": "c:\\ncs\\v3.1.1"
    },
    {
      "version": "v3.1.0",
      "path": "c:\\ncs\\v3.1.0"

If not, can you please try to run the following command? (does require a standalone installation of nrfutil):

nrfutil sdk-manager toolchain launch --terminal --ncs-version v3.1.1 (this will open a new window, use this one for the rest of the commands)

cd into the root folder of ncs v3.1.1, e.g. c:\ncs\v3.1.1

run "west update" and wait for it to finish. Does it indicate any errors? When this is done, close VS Code and relaunch it. Does it work now? If not, can you generate the support information once more, and upload this as well?

Best regards,

Edvin

Vishveshwaran — Mon, 12 Jan 2026 08:22:32 GMT

I do work on windows,and moreover yea it is a path issue, to be exact the nrf sdk is not getting directed to the vs code, the machine is not recognizing the sdk, that is the exact issue. the issue started when i tried to update west in my terminal using west update. and that process also dint complete fully because i faced network issues.

RE: Help needed with Pristine build in vs code

IoT-Dani — Sat, 10 Jan 2026 13:21:13 GMT

I think this is a path issue with nRF Connect. Do you have additional information?
Did you update the extension lately? I assume you work on Windows, don't you?

As I wrote, a “Generate and Build” solved it with my project.

RE: Help needed with Pristine build in vs code

Vishveshwaran — Sat, 10 Jan 2026 11:35:41 GMT

i am using V 3.1.1 and my build configuration is configured to that only. and i tried creating a new one by deleting the old one but still same response

RE: Help needed with Pristine build in vs code

IoT-Dani — Sat, 10 Jan 2026 11:16:00 GMT

Hi Vishveshwaran

This happened to me if I tried to pristine build from a build configuration inside VS Code that references an SDK that is not installed anymore. The solution was to edit the build configuration and do a “Generate and build.”

Kind regards, Dani
